This very special expedition combines challenging trekking and camping in the shadow of the world’s third-highest mountain, with a unique behind-the-scenes insight into our work to save one of the world’s most threatened mammals, the pygmy hog.

Once thought to be extinct, the world's smallest pig is also one of the most threatened mammals on Earth.

Found only in the tall grasslands of Assam in India, the pygmy hog was rediscovered in 1971 when a group was found sheltering from a grassland fire in a neighbouring tea plantation.

Since then, Durrell have been working in Assam to save pygmy hogs from extinction through captive breeding and release programmes and grassland restoration and management.

How your donation can help:

£6,500 = 50 camera traps. Remote camera networks help us monitor pygmy hogs that have been released into the tall grasslands of Assam.

£1,500 = eight transmitters. Some of the pygmy hogs released into the wild are fitted with radio trackers, which we locate using transmitters. The data provides valuable information on their behaviour and range, which helps us with future releases.

£1,500 = PPE for 300 community members. We provide personal protective equipment for members of the local community who are helping us to remove invasive tree species in Manas National Park.

£1,000 = 1,000 trees removed from habitat. Pygmy hogs depend on their grassland habitat for survival, hiding in the long grasses. They are too easily seen and killed by predators in woodland areas where trees have become established.
